[Q] Unlock bootloader wipes all data ?

Hello.
Im abit new to the forum but here goes.
Ive read tons of posts everywhere and there aint any exact answers anywhere to find.
In the past ive never known about the TA and DRM so happy as i am i just unlocked the bootloader on all the phones and still happy. The latest phone is the Xperia Z1. It has been abit buggy to say the least but im hoping software updates will cure this.
Anyway, i rooted my phone and unlocked the bootloader on the .681 firmware and now i am on .757 firmware. Using Doomlords kernel. I thought id check if i could backup my TA partition after unlocking the bootloader. And from what ive read its suppose to be wiped when you unlock the bootloader.
Well it was no problem backing up the TA partion. All files were there and it came out with no errors. So the question, how is this possible ?
I posted this same thing in General, sorry for that but i posted it here now so if a moderator finds this post in general then please delete it.

If you Unlocked your Bootloader without Backup TA (DRM keys) first, then your DRM Keys are lost forever and you can Backup TA how much you want but there is no DRM Keys at all. The application to Backup TA do not give errors because you can backup partitions with or without DRM Keys, in the case you want switch between Locked and Unlocked Bootloader.
So long story short, you don't have DRM Keys, your warranty is lost forever, you cannot Update via OTA,PC Companion or SUS.

The one time I had to use my warranty there was no problem with missing TA.
So there is hope for people without it

dunno if the previous author saw what i wrote in my post but when i relocked my Xperia V using flashtool i could update with the pc companion or sony update or whats it called nowdays
And funny thing is, i actually have a case at Sony about this phone since i do have some issues with it but i think thats software related since ppl have been getting all sorts of errors from the KitKat firmwares. But i said how it was that i have unlocked bootloader and all that and she replied that my warranty was still valid and i could send it in for them to test it.
And i need to say this. Since sony posts an official way on their webpage, for ANYONE to read about how to unlock the bootloader and they also supply the code for unlocking it. Then i think it shouldnt affect the phone in any way or brake the warranty. (Sure it does say something about that, but all aint reading stuff like that). So if a developer wanted to unlock the phone. Why not have them contacting sony instead.
And surley, DRM keys (i just think sony shouldnt even bother having them) can be put back in if you let Sony do it. They put it there in the first place you know. And in the lovely electronic world we live in we all know that, if Sony can put thoose there, anyone could do it with the knowhow. But since the keys dont really mean anything, not that ive noticed you could really think about what use they actually do. And Sony knows that if ppl cant have the phone it was meant to be even with a unlocked bootloader, they will probably get some other phone or just whine hard enough so that Sony makes a software where everything works the same way with locked or unlocked. Camera stopped to work if you unlocked before 4.3 right ? What can you read about that like everywhere ? Loads of whining and Sony released a software that works just as good with locked or unlocked.
God damn this became a long post. So with this said im just saying. Why even bother in the first place having DRM keys if the rules dont apply anyway ? An everyday user doesent even need them either, he or she doesent even know what rooting or unlocking is anyway. And the ones that do know about it, also know about how to whine to get sony to fix the errors wich an unlock will produce

[Q] What's wrong with my camera, HELP please

Hi
I am running stock 14.5.A.0.270, rooted and bootloader unlocked. Sony Xperia Z1
My camera app opens up, the camera button on the side of the phone even works. You push the capture area and front camera freezes and normal camera just shows me two buttons and won't do anything.
Please help I do not know what to do. There were a few other threads with a similar problem but I haven't found the resolution yet. Is it because bootloader is unlocked, I have read that I should restore the ta partition and relock my bootloader but I thought I will try here first.
I thought it would be fun rooting and flashing phones but so far just a big timewasting headache. I was on CM12.1 before , nightlies they were good but then it wouldn't recognise my sim card.
RR I tried but I got stuck on the bootloop.
Now I am back on a stock and my camera doesn't work
Help me please, I want to learn more
Many thanks for your time

Sorry I'm a bit late it seems but i had the exact same problem, camera wont focus and take pictures, video did still work depending on firmware but unfocused. Chances are your asking here because you lost your TA partition and DRM keys, which is most likely the cause
Solution:
make sure your phones bootloader is UNLOCKED
1. Grab flashtool
2. open Xperifirm via flashtool
3. look for 14.3.A.0.757 firmware (for journalists and media) (MUST be downloaded via xperifirm)
3. Download and unpack automatically, let flashtool do its thing til its ready
4. Relock your bootloader, DO NOT start your phone or touch your phone, keep it in flashmode
5. flash the firmware you just downloaded (14.3.A.0.757)
6. start your phone, camera SHOULD be working
7. Unlock bootloader and Flash any .ftf you like, tick EXCLUDE in the box that says .TA when you flash / if its available
8. Enjoy

Is this weird or normal?

I searched high and low for solution of my problem but i couldnt find the right solution to my problem that's why I'm starting this thread.
Phone- Xperia Sp C5302
Stock Kernel
Rooted
Philz Touch recovery installed
Nandroid backup made using TWRP
Tried to unlock bootloader- Problem starts from here........
Initially phone rebooted normally but couldn't detect sim and signal.
Then phone started rebooting after few minutes . Stay on for a while then reboot again till battery died.
Now battery not charging, phone showing no life, no led, no vol up+power, vol- power , vol up+vol down+power work
Tried everything I know plz help and plz explain slowly and calmly.
THANKS IN ADVANCE.
EDIT:
Used wall charger 2amp for charging left overnight no red led or anything as described in other posts
Connected to laptop left for about 4 hours no nothing.
Tried to connect in fast boot not detected.
Any more ideas guys at least give some pointer for what to do or is my Sp is actually dead ? And I can't restore my backup? Plz guys help
EDIT: Pressed the small button at the back and the phone came back to life YESSSSS........

Now the phone isn't showing imei no. or sim or network. But when restarted it imei and network came back magically. So I thought the problem is solved to confirm it I switched phone off again then switched on then imei and network gone again and also baseband isn't showing too (I'm sorry if it is the same thing I'm a newb to this stuff)
Then again I restarted the phone number it came again. I don't know what to do in this situation. I just wanted to unlock bootloader and install xenon hd rom in my Xperia Sp.

Try flashing stock ftf with Flashtool.
If the problem gets solved, then start with the new ROM.

Use the method answered by the previous post. But I will add into that
You can use the flashtool to flashing everything stock but please dont flash System and Kernel. If you flashed a custom recovery and want it to stay untick Fotakernel as well.
This should fix your problem without having to deal with the stock ROM.
But if problem persists then I would suggest a complete stock ROM flash.
Huge chance that the process of unlocking your bootloader is faulty. Are you sure that it went without errors? Anyway you might also wanto to try to relock and then unlock the bootloader again

@Zenith I left the phone idle for sometime now it's OK ish . I've made a nandroid backup but can u tell me plz which folder contains imei and other important stuff so I can make a backup of it too.
BTW I think my bootloader is not correctly unlocked coz pc companion is detecting my phone bravia engine is there gracenote is working. But in service menu under configuration I found: Bootloader unlocked: Yes.
Previously it was Bootloader unlock: Yes. So is it unlocked or not if not then how to unlock?
I've followed sony's official unlocking method.

You don't need to backup imei. It will stay the same no matter what ROM you use.
and You can use Titanium Backup to backup all your important apps and data. But do not backup/restore system apps.
and in the service menu;
"Bootloader Unlock allowed - Yes" means that your Bootloader is Locked, and you can unlock it.
"Bootloader Unlocked - Yes" means that your Bootloader is unlocked.
Bravia engine shouldn't work if your BL is unlocked, so something must have gone wrong in the process.
Follow what's said in post #4.

@Zenith Thank you for your wonderful suggestion i will do as u say. bt one big noob ques- Do i have to dload a ftf file to flash to stock cant i use my backup or someyhing from it to restore?
@TechnoSparks yeah i think you are right about my bootloader bt isnt there something to check if BL is unlocked correctly. Btw when i requested to unlock BL in fastboot nothing really happened apart from
<Bootloader > Unlock phone requested
OKAY [15.725s]
finished. total time: 15.725
Then restared approx every 10 min or so till battry went flat and phone being dead untill i reseted it via pin

Yes, you have to download the ftf file.
Use this one.
and don't use the latest version of Flashtool, use the "0.9.18.5" version.

@Zenith Thanks bro bt my model is C5302 will it be compatible?
And i just dloded 0.9.18.6 version. its not latest 0.9.19.0 ver is latest.
So do i have to dload again? (connection limited bandwith n slow speed)

@Zenith Sorry bro for bugging you again n again bt u r the only person who showed some intrest in this post and helping me.
Btw ive founded this"https://drive.google.com/file/d/0B-mh6JO-ztBfaGZ6UE1QanFzRTg/edit?usp=sharing" C5302 Indian generic 12.1.A.1.201 [FTF] Is it better?

You should flash ftf specified for C5302 then.
Download the C5302 variant that you prefer from here.
And try flashing with the Flashtool you have. If it doesn't work properly, then uninstall it, and install the 0.9.18.5 version.
Some members including me faced some problems on the next 2 versions of flashtool. So yeah..

Even you can flash C5303 ftf on C5302. I personally use Singapore variant .207. It has got least bugs and it is fast and much bloatware free.
P.S. Dont flash .201 it has got a lot of bugs.

Reversed screen rotation after fw swap c6916 (14.5.B.0.247) to c6906 (14.6.A.0.368)

Hi folks,
I've upgraded/replaced the original TMobile firmware (14.5.B.0.247) on my Xperia Z1s (c6916) by c6906 Customized US (14.6.A.0.368). Everything works fine except few things like:
1) screen rotation - when i try to rotate the screen into the landscape mode - it turn the screen in opposite direction/backwards. Looks like the sensor readings get reversed? It was working fine before the upgrade, hence it looks like a software issue. Any ideas how to fix it?
2) device memory is twice less but it is kind of expected because original Z1 has only 16 Gb of storage onboard. Is there any way to fix that?
Thanks.

ok, here is a "solution":
The C6906 "/etc/sensor_def_qcomdev.conf" must be replaced by C6916 version. The same applies to CyanogenMod 12.1. C6916 have different settings for few things.
I downloaded TMO firmware, extracted system.sin and replaced the file on my phone running CyanogenMod 12.1 - after reboot rotation works perfectly but it will get broken as soon as i upgrade the firmware

how did nobody catch that this dude managed to flash a different firmware on a phone that is supposedly NOT unlockable? Shefys, you need to explain exactly what you did. In another thread you said you unlocked your Z1s c6916 on developer.sony.com and i tried it, but there was no Z1s option. Followed the steps anyways by selecting Xperia Z1 but the unlock command failed citing not allowed.

How you did this? I hard bricked my Xperia Z1S putting the 5.1.1 fimware, I needed to buy a new board because I had no solution.

hi, i wasn't aware that you cannot unlock z1s booloader. I just went to the developer site, registered, submitted my imei (as a Z1) and got a link/key to unlock it.... maybe my imei was lucky. Sorry, folks. Right now I'm running CM12 on my Z1s. Can provide photos if you want to
Before unlocking the bootloader, i was running C6906 official firmware on my phone because it was newer.

Yes please post pics. I tried unlocking my z1s as a z1 just like that but it didn't work. The fastboot command to process the unlock returned a "not allowed" error.
If you can get to the service screen, there is a section where it says "unlockable: no". (Or yes). Can you post a picture of that?
How did you get on the 6906 firmware?

after you take the link and after that you take the unlock code just have to unlock with flashtool:
1.) create a folder in the flashtool folder with your device code ... mine is : D:\Android\Flashtool\custom\mydevices\CB5A1WPPTA
2.) inside the folder, create a file called ulcode.txt , in the file just copy the unlock code
3.) open flashtool (be sure that your phone have enable usb debug and connected) and press BLU (bootloader Unlock)
4.) after that a window will appear with your code and the phone id, you select unlock and now you have the xz1s unlocked...
BE AWARE: in my case, the camera doesnt focus after unlocked and video just doesnt work...
for the rom, i think you could take it using xperifirm and installing with flashtool

I'll have to try this and report back. I understand that unlocking the bootloader causes issues with the camera, but does the issue get resolved by flashing a ROM? Or does it stay broken?
